Application filed April 19, 1899. Serial No. 713,650. (No model.) I

To all whom, it may concern:

Be it known that I, JONATHAN GODFREY, a citizen of the UnitedStates,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inMachines for Making Paper Boxes; and I do hereby declare the followingto be a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to certain improvements in machines forautomatically making paper boxes, and has for its objects to manufacturesuch boxes economically, rapidly, and uniformly, while at the same timethese articles shall be of considerable strength, so that they may beused for the purpose of containing and shipping heavy cartridges of thewellknown Mauser type.

With these ends in view my invention consists in the details ofconstruction and combination of elements, such as will hereinafter befully described and then specifically be designated by the claims.

In the accompanying drawings, which form a part of this application,Figure l is a plan of my improved machine; Fig. 2, a section at the linea a of Fig. 1; Fig. 3, a section at the line b b of Fig. 1; Fig. at,asection at the line 0 a of Fig. 1. Figs. 5, 6, 7, 8, and 9 are detailbroken plan views illustrating, respectively, the position of thevarious tools which operate immediately upon the box-blank in theperformance of the successive operations necessary for the completion ofthe box and Figs. 10 and 11 are detail broken sectional elevations onthe line 61 d of Fig. 9, illustrating the position of the setting-tools,respectively, before and after the operation of setting. Figs. 12, 13,14, and 15 are detail perspective views illustrating the several stepsor folding operations which are performed in the manufacture of the box;Fig. 16, a detail plan of the blank from which the box-body is made, andFig. 17 a detail plan of the blank from which the bottom of the box ismade.

Similar numbers and letters of reference denote like parts in theseveral figures of the drawings.

The box which my machine makes must lie formed of stout material, mustbe strongly put together, and must be rapidly made; and it is with theseends in View that I have contrived the various mechanisms and tools, alloperating automatically, as will be hereinafter set forth.

The body of the box and the cover are made in precisely the same manner,the only differ- 6o ence being that the cover is a trifle larger, andthe description to be given will apply equally as well to one as to theother.

For convenience in explanation I Will refer to the article made as thebox, and would .65 say that this box is formed from two blanks,oneabody-blank, which is wrapped around a mandrel, and the other abottom-blank, which is placed on top of the mandrel, so that the edgesof the body-blank project beyond the same, these edges being properlynotched,so that when they are closed over and down upon the bottom-blankthe ends and sides 7 will meet in a proper miter-joint.

There are several operations necessary in the manufacture of this box,namely: feeding the bottom-blanks and delivering them on top of themandrel or forming-block, bending the body-blank around the mandrel withthe free ends of this blank overlapping each other at one end of themandrel, closing over the ends and sides down against thebottomblank,the parts thus coming in contact being previously coveredwith glue, stamping or corrugating the bottom of the box thus formed 8 5so as to firmly set these glued portions together, and finallywithdrawing the mandrel and tools and stripping the box and deliveringthe same into any suitable receptacle. It is immaterial in what way theoperations of clos- 9o ing Over the glued edges of the sides and endsagainst the bottom-blank are performed, but for the purposes of savingtime and space and in Order that the various cams and mechanisms may bemore conveniently timed'I have constructed my machine to perform thesevarious operations in the manner presently to be set forth, and Itherefore do not wish to be limited in this respect.

For the purposes of a better understanding of my improvement I willdescribe the same as near as practicable with reference to the order inwhich the several operations are performed.

1 is the bed of the machine, 2 the main shaft, jonrnaled in boxessupported on the bed, and 3 the power-pulley, secured on this shaft. 4 56 are bevel-gears secured on this shaft and meshing with bevel-gears 7 89, secured on shafts 1O 11 12, journaled within suitable boxes supportedby the bed and by the upper table 13 of the machine. These shafts 10 1112 are vertically disposed and are at right angles to the shaft 2. Theshaft 12 carries cams A B O D E F, the shaft 11 carries the cams G H I,and the shaft 10 carries the cams J K.

14 is a well capable of snugly containing the bottom-blanks 0c andsupported in vertical disposition by any stationary portion of themachine in a plane immediately above the plane of the mandrel 15 whenthe latter is in its uppermost position, as will be presently explained.This mandrel is mounted upon any suitable block 16 capable ofreciprocation within ways, and within the lower portion of this blockare journaled friction-rolls 17.

L are cams carried by the shaft 2 and kept in contact with the rolls 17by means of springs 18, whose ends are connected with said block and thebed of the machine, so that it will be readily understood that therevolution of these cams will effect the elevating and lowering of themandrel. A portion of the periphery of these cams L is concentric withthe shaft 2, so that the mandrel will remain in elevated position duringthe operation of forming the box, and the bottom-blanks are deliveredfrom the well 14 and deposited upon the mandrel when the latter is insaid position.

19 is a push-finger or slide capable of reciprocation within suitableways at or about the plane of the bottom-blank in the well. The forwardextremity of this finger is cut away to accommodate the blanks and isprovided with ledges 20, and this push-finger really constitutes thebottom of the well. In normal position this fin ger is withdrawn, sothat the lowermost blank rests within the cut-away portion upon theledges 20, and when said finger is pushed forward it will then extendthroughout its area across the bottom of the well, thus closing the sameuntil the finger is retracted to normal position, whereupon thelowermost blank will then drop into the cutaway portion and rest uponthe ledges, as before set forth.

21 is a bell-crank lever, the outer or long leg of which is pivoted to alink 22, which latter is in turn pivoted to the finger 19, and thislever is pivoted at its knee around the rockshaft 49, presently to bedescribed, while the rear or shorter leg of this lever is provided witha roll 23, which bears against the cam I. As the long radius of this camI acts against this lever the push-finger will be projected to deliver ablank above the mandrel, and the nature of the cam is such that theparts actuated thereby will remain in the position which caused theprojection of the finger until the blank has been deposited upon themandrel, as will now be explained.

24 is a bracket supported by any suitable stationary element, and 25 arepins which project loosely through said bracket and are joined at theirupper ends by a cross-piece 26. This bracket overhangs the mandrel, sothat when the pins are depressed they will be driven against the blankthat is held by the push-finger, thereby forcing said blank down uponthe mandrel, the blank yielding, owing to its flexible nature, to permitof this.

27 is a frame which is supported on the table 13, and 28 is a rodjournaled within cars 29, extending from said frame. 30 is a crankextending rearwardly from said rod and provided at its extremity with aroller 31, which rests upon the cam E, and 32 is a crank which extendsfrom this rod 28 and is pivoted at its extremity to the link 33, theother end of the latter being pivoted to the cross-piece 26.

34 is a coil-spring around the rod 28 and having its extremitiesconnected, respectively, with a stationary element and with the crank30, whereby the latter is normally depressed to keep the roller 31always in contact with the cam E.

Presupposing the push-finger to have been projected, whereby a blank isheld in its outer end immediately above the mandrel, the cam E nowoperates to elevate the crank 30, thereby forcing the pins 25 downagainst the blank, whereby the latter is carried and deposited upon themandrel. The next operation has reference to the delivery of thebody-blank and to the wrapping of the same around the mandrel. The innerwall of the body-blank is covered with glue near the bottom edge or,more properly speaking, the edge which, though uppermost around themandrel, is to be at the bottom of the completed box.

35 is a block capable ofsliding freely within ways in the table 13 andcut away, as seen at 36, at its inner end, while the other end carries aroll 37, which is kept in contact with the cam K by means of springs 38,secured, respectively, to said block and to the table. Mounted in waysupon this block is a closingover die 39, which is confined by means of ascrew-bolt 40, which passes through an elongated slot 41 in the die intosaid block, so that it will be clear that said die is capable of alimited sliding movement independent of said block. 42 is a roll whichis carried at the outer end of this die 39 in the same horizontal planewith the cam .I, and 43 are springs whose ends are secured,respectively, to the die and block, whereby said die is kept in anormally-retractcd position. The body-blank :1] after the properapplication of glueis placed edgewise upon the table 13 immediately infront of the block 35 and with one corner abutted against the gage 44,secured to the table, and as the block advances, owing to the action ofthe cam K, the blank y will be forced against the mandrel and will bebent around the letter in U shape by reason of the cooperation betweensaid mandrel and the cut-away portion 36 in the block.

The blank y is shaped and notched as shown at Fig. 16, and afterundergoing the operation j ustdescribed the position of this blank withrespect to the bottom-blank on the mandrel will be as shown at Fig. 12,by reference to which it will be seen that the edges of the blank 3project above the plane of the bottom-blank 00, while it will also beclear that the object of the notching of the blank is to cause the sidesand ends of these projecting edges of the blank y to meet in amiter-joint when these edges are closed over upon the blank .70, as willbe presently explained. Immediately after the cam K has operated toeffect the result above described the cam J will strike against the roll42 and will force the die 39 forward to close over the edge of the blanky at the end thereof. I have shown at Fig. 5 the position of the varioustools immediately after the operation of the block 35 to bend the blankaround the mandrel, and by reference to this figure as well. as to Fig.6 it will be observed that I have illustrated this end die 39 and theside-closing dies (presently to be explained) as having, to allappearances operated simultaneously; but in reality the die 39 operatesto perform its function before the edges of the sides of the blank y areclosed over, although, as will appear later on, the order in which thesevario us operations on the blank 3 are performed is really immaterial.

For the purpose of closing over the glued edges of the blank y along thesides thereof, I provide two blocks 45 46, capable of sliding freelywithin ways on the table 13, and loosely pivoted to the outer ends ofthese blocks are levers 47 48, the inner ends of which lovers are keyedto rock-shafts 49 50, which latter are vertically disposed and arejournaled within suitable bearings in the bed 1 and frame 27. Also keyedto these rock-shafts 49 50 are cranks 51 52, which are provided at theirfree ends with friction-rolls 53 54, that are normally kept incontactwith the cams D C by means of spring 55, whose ends are secured,respectively, to crank-pins 56 57, projecting from these rock-shafts. Itwill thus be readily understood that the levers 47 51 and 48 52 are ineffect single levers, owing to the fact that each pair is connected, re-

spectively, with the rock-shafts 49 50, and therefore it will be clearthat the cams G D will effect the swinging movements of theselevers,whereby the blocks 45 46 will be thrown toward the mandrel orwithdrawn therefrom. As these blocks are forced against the mandrel theywill close over the side edges of the blank y down against thebottom-blank at, so that the position of the various tools will be as isshown at Fig. 6.

58 59 are properly-shaped blocks capable of sliding freely within waysin the table 13 and located immediately inside the blocks 45 46. 6O 61are levers whose outer ends are pivoted loosely to these blocks 58 59,while the levers themselves are pivoted at or about their middleportions around the rock-shafts 49 50. The rear ends of these levers areprovided with friction-rolls 62 63, which are kept normally in contactwith the cams A B by means of coil-springs 64 65, whose ends aresecured, respectively, to said levers and to the frame 27. The cams A Bare so timed with respect to these levers that the block 59 will beoperated slightly in advance of the block 58, so that as the block 59 isthrown against the mandrel it will cause one of the free ends of theblank to be bent around the mandrel, while immediately after this theblock 58 will bend the other free end of the blank around the mandreland overlapping the first-mentioned end, so that the various tools willnow be in the position as shown at Fig. 8, while the box itself as thusfar completed is illustrated at Fig. 1 4.

66 is a block capable of sliding freely within ways in the table 13, andcarrying at its rear end the roller 67, which is normally kept incontact with the cam H by means of the springs 68, whose ends areconnected, respectively, with said block and'with a stationary part ofthe machine. Mounted within ways on top of this block 66 is a closing-indie 69, confined in position by means of a threaded pin 70, which passesthrough an elongated slot 71 in said die into said block. The rear endof this die carries a roll 72, which is in the same horizontal plane asthe cam G. The die 69 is kept in a normally-retracted position by meansof springs 73, whose extremities are secured, respectively, to said dieand block. The rotation of the cam II will force the block 66 firmlyagainst the overlapping edges of the blank y, and immediately after thiscam G will operate to throw the die 69 toward the mandrel, thus closingdown the projecting edges at the end of the partially-completed boxformed by the overlapping ends, the said parts being now in the positionshown at Fig. 9.

It will be observed that the dies which operate to close over the edgesof the blank y both'at the sides and at the ends are beveled upwardlyfrom their outer ends, this beveled portion being denoted in allinstances by the reference-numeral 74, while the mandrel iscorrespondingly beveled on its upper surface 7 along its edges, as seenat 75.

After the operations heretofore described have been performed theposition of the mandrel with respect to the closing-in dies is as isshown at Fig. 10, where I have illustrated the position of the end dieswith respect to such mandrel, and the cam L will as it continues torevolve now throw the mandrel upward, so as to force the edges that havebeen lued over against the bottom-blank upward and firmly compress thembetween the mandrel and the closing-in dies, the bottom of this blankbeingby thismovement forced upward, so that the parts will be in theposition as shown at Fig. 11. This upward movement of the mandrel willcause the glued edges of the blank yand the blank 03 to be firmlycompressed together between the beveled portions of the dies andmandrel, thereby eifectually setting these glued portions, while thethrowing up of the body of the blank x will cause these compressed gluedportions to assume a position substantially parallel with thebottom-blank, so that in the completed box the entire bottom will be insubstantially one plane. After these various operations have beenperformed the cams heretofore mentioned will by their continuedrevolution effect the withdrawal of the various blocks, dies, andmandrel, and as the latter is withdrawn the box will be strippedtherefrom by means of the stripper-plate 76, which is secured upon thetable 13 around the mandrel and upon which the blank y rests during theformation of the box. After the mandrel has been withdrawn the boxremains resting upon the stripper-plate and is projected therefrom intoany suitable receptacle by the mechanism which I will now describe.

'77 is a kicker-rod supported within suit able bearings 78 and capableof a free movement therein, the inner extremity of said rod carryingprongs 79, while the rod itself is in clined in the direction of thestripper 76.

80 is a bell-crank lever pivoted at its knee to any suitable bracket 81,supported by the table 13, the inner or short leg of this lever carryinga roll 82, which is kept normally in contact with the cam F by means ofthe coilspring 83, whose ends are secured, respectively, to said leg andany stationary part of the machine. The long leg of said lever ispivoted to a rod 84:, the other extremity of the latter being connectedto a block 85, secured to said kicker-rod 77. After the completed boxhas been left supported upon the stripper, as hereinbefore set forth,the cam F will operate to cause the kicker-rod to be suddenly projectedtoward the box, thereby kicking the latter off the stripper-plate intoany suitable receptacle.

From the brief description which I have heretofore given a generalunderstanding will be had of the construction and operation of myimprovement; but I will now more particularly describe the manner inwhich a box is made upon my improved machine.

Glue is applied to the blank from which the body of the box is to bemade along certain edges, as shown at 86in Fig. 16, and the notched edgeof this blank is uppermost when said blank has been bent around themandrel.

The various cams heretofore mentioned are so constructed and timed thatthe operations of disposing the blank y around the mandrel and theclosing of the projecting glued edges down upon the blank :0 areperformed in a certain order; but it will be clear that it is immaterialwhether the side edges are turned over simultaneously or in succession,or whether the end edges are turn ed over si multaneously or insuccession, or whether the sides and ends are turned over all at thesame time. It will accordingly be understood that the tools and dieswhich are the immediate factors in forming the box are the chief andmost important elements of my machine, while the cams and theconnections between the latter and these tools or dies are secon; daryfeatures, which may be varied greatly without departing from the spiritof my invention. I

The operator keeps the well 14 supplied with the blanks .70, and as soonas the cam L has operated to throw the mandrel up into position thepush-finger 19 is operated to carry the lowermost of these blanks intoposition immediately above said mandrel, whereupon the plunger-pins 25descend and force said blank down upon the mandrel. After a glued blanky has been placed in front of the block 35 the cam K operates to projectthis block, thereby wrapping this blank around the mandrel, with thefree ends of said blank projectmg in parallelism at the opposite end ofsuch mandrel, while the glued edges will extend above the plane of theblank 00, the position of the various tools and dies being as is shownat Fig. 5. Immediately after this operation of the block 35 the cam Jwill operate to throw the die 39 against the projecting glued edges ofthe blank y at the closed end of this blank down against the blank 00,while at substantially the same time the blocks 45 46 will be forcedagainst the sides of the blank y by the action of the camsD G and willclose over the projecting glued edges of these sides down against theblank x, the parts being now in the position as shown at Fig. 6. Thesliding blocks 58 59 are now operated by means of the cams A B, theblock 59 being operated slightly in advance of the block 58, so that oneof the projecting free ends of the blank .y will first be wrappedclosely around the end of the mandrel, whereupon the block 58 will causethe other end of said blank to likewise be' wrapped around the mandrel,but

overlapping the first-mentioned end, this operation being clearly shownat Fig. 7, while the position of the various tools and dies after theseprojecting ends have been properly disposed around the mandrel is as isshown at Fig. 8. I the block 66 against these overlapping edges,

The cam H now operates to throw thereby firmly setting the gluedportions, while immediately after this the cam G will force the die 69against the upwardly-projecting edges of these overlapping portions,thereby forcing these edges down against the bottom blank 00, theposition of the several tools and dies being now as is shown at Fig. 9.

It will thus be readily understood that a box has been completely formedby the operations heretofore described; but since the box is made ofheavy substantial material it becomes advisable to apply considerablepressure to the glued portions in order that they may be more firmlyunited, and I therefore have recessed the mandrel near its edges, asshown at 75, while those portions of the'dies that have operated toclose over the projecting edges of the blanky are undercut, so as toafford recesses 74, similar to Zthe recesses 75. The parts 'being now inthe position as shown at Fig. 10, the cams L now operate to throw themandrel slightly upward, thereby crushing the glued portions firmlywithin these recesses, as shown at Fig. 11. This crushing of the gluededges has the effect to slightly raise the bottom of the box, so thatthe edges are practically countersunk, so to speak, and the effect ofthis is to make the bottom of the box perfectly level and with noprojecting portions near the edges, thus greatly strengthening the boxand adding materially to its neat appearance. The several tools and diesall remain in position around the mandrel until the box is completelyformed, whereupon the various cams will operate to withdraw the blocksand dies which have operated upon the sides and ends of the box, thusleaving the completed box upon the mandrel, with the edge near thebottom of the mandrel resting upon the stripper-plate 76. The cams L nowoperate to withdraw the mandrel, after which the cam F will operate tocause the kicker-rod 77 todart-toward the box, thereby projecting thelatter into any suitable receptacle, whereupon the mandrel will again beelevated into position by means of the cams L, and the operationsheretofore described will be again repeated, and so on.

While I have illustrated and described my improvement as used for thepurpose of making paper boxes from two blank portions, it will beperfectly clear that the box could be made from a single blank.

sition which the bottom-blank would occupy with respect to thebody-blank in case the two were to be in a single piece; but I greatlyprefer to make the box from two blanks, owing to the great waste whichwould occur 'in the stock were the blanks to be cut in a single piece.

Boxes of various sizes may be made on a single machine by substitutingdifferent sizes of mandrels and byusing different-sized tools and diesand making the proper adjustments I have therefore illustrated at Fig.16 by dotted lines the po-' sides of the box are formed, and means forclosing the projecting edges thus formed down against the bottom-blank,substantially as set forth.
